In the first embodiment, the abutting portion 21 is integrally formed on the shielding fixing piece 2. For example, the abutting portion 21 is punched out of the plate-shaped shielding fixing piece 2 by stamping technology, but it is not limited thereto. In other embodiments of the present invention, the abutting portion 21 can be a separate element and be fixed to the shielding and fixing piece 2, or be made on the shielding and fixing piece 2 by other forming means, as long as the abutting portion 21 can form an electrical connection with the shielding and fixing piece 2. In addition, as shown in FIG. 4, at least one insertion slot 13 is provided in the connector body 1 (such as the insulating base 12), so that the shielding fixing piece 2 can be inserted into and positioned in the insertion slot 13, but, in other embodiments of the present invention, the shielding fixing piece 2 can be fixed in the connector body 1 in other ways.

In addition, as shown in FIGS. 1 to 4, at least one end of the shielding and fixing piece 2 can be provided with a positioning piece 22, and the positioning piece 22 can be attached to a bearing portion 123 of the insulating base 12.

Afterwards, inject the liquid conductive plastic part 33 into the filling space 340 by injection molding. contact portion 331), but not limited thereto. In other embodiments of the present invention, the conductive plastic part 33 and the insulating part 34 can be fixed on the signal terminal 31 and the ground terminal 32 by embedding, assembling or other means, or, only the conductive plastic part 33 or the insulating part 34 can be provided, which will be described first.

1 to 7, when the terminal set 3 is assembled to the connector body 1, the contact portion 331 of the conductive plastic part 33 can be in contact with the abutment portion 21 of the shielding fixing piece 2, so that the ground terminal 32 and the abutment portion 21 are indirectly electrically connected (that is, indirect contact), but not limited thereto. In other embodiments of the present invention, the ground terminal 32 can directly contact the corresponding abutment portion 21, for example, the ground terminal 32 and/or the abutment portion 21 are respectively provided with a bending section, so as to achieve mutual contact effect through the above-mentioned bending section. In other words, at least one grounding terminal 32 of the present invention can directly or indirectly contact the abutment portion 21 of the shielding fixing piece 2 located in the same receiving space 10 , so that the connector C can form the first grounding path for grounding, that is, the metal cover 11 , the shielding fixing piece 2 , the conductive plastic part 33 and the grounding terminal 32 . In addition, when the connector C has multiple terminal groups 3 , a shielding fixing piece 2 can be placed between any two adjacent terminal groups 3 , so that the two adjacent terminal groups 3 are less likely to interfere with each other.

The configurations of the portion 114 and the housing positioning portion 41 are also interchangeable. After the connector body 1 is assembled to the housing 4, the cover positioning portion 114 will be combined with the corresponding housing positioning portion 41. For example, the aforementioned protrusion can be inserted into and fixed into the opening, so that the connector body 1 cannot be easily separated from the housing 4. In this way, the connector C can form a second grounding path for grounding, that is, the housing 4, the metal cover 11 and the shielding fixing piece 2. It can be seen that through the overall structure of the present invention, no matter the first grounding path and/or the second grounding path, they can be respectively connected with the grounding circuit of the circuit board or other grounding components to form a good grounding path, so that each terminal group 3 can achieve a good shielding effect, reduce the interference of each terminal group 3 from adjacent terminal groups 3 when transmitting high-frequency signals, and make the connector C have a more stable performance when performing high-frequency and high-speed transmission.
